Hi Guys!
I´m from Brazil, and I have the same problem that the User RetrOS.
Everdrive 64 is V2 US
My Console is N64 US too.
Bootloader V3
I user mini SDcard 8GB samsung Original with SD adapter. (maybe that´s the problem I think)
I´ve created in the SD root:
ED64 (folder with the last OS64.v64) version 1.29
For test, just few roms, like Zelda OOT, Mario Kart 64 and PaperMario 64
Appears a black Screen too.
Krikzz, can you help us about this issue?
